Look at it this way, buy the Needswings duel intake and you get the best intake, the most air flow of all the intakes homemade or by so called manifactories that most likely stole the design from Needswings.
Needswings is teflon coated in and out ,but if you want it thermocoated,needswings can do that too.
one day when you sell your car you can sell the NW intake and get some of your money back,
like a lot of people on this fourm can say "I have a Needswings intake" when ever you say that everyone listens, just get the best and forget the rest. jim
